Provably fair results
The casino commits to a seed hash and lets you recompute results. Bets still run in its own system.

Blockchain casinos: what actually runs on the blockchain
Every crypto casino uses a blockchain for deposits and withdrawals. Blockchain casino usually means more than that: game results you can check, or bets settled on-chain.
The label is loose, so the useful question is which part runs on-chain. Below: the parts that can, what each lets you verify, and the casinos listed as blockchain casinos in our reviews.

Short answer
What is a blockchain casino?
A crypto casino that uses a blockchain beyond payments, usually for provably fair results you can recompute, and at some sites for bets settled by smart contracts. Deposits and withdrawals are on-chain at every crypto casino, so they do not make a casino a blockchain casino on their own.
On-chain or not
Which parts of a crypto casino can run on-chain
Most balances are off-chain. Between deposit and withdrawal, your coins usually sit with the casino.
| Part | On-chain? | What you can check |
|---|---|---|
| Deposits and withdrawals | Yes, at every crypto casino | The transaction on a block explorer |
| Game results | Sometimes, as provably fair seeds | Recompute the result from the seeds |
| Bets and payouts | Only at dApp casinos | The contract call and its payout |
| Your balance between bets | Usually not | Nothing: it is a number in the casino's account system |

Blockchain casino FAQ
What is a blockchain casino?
A crypto casino that uses a blockchain beyond payments, typically for provably fair results or smart contract bets.
Are my funds safer at a blockchain casino?
Not by default. At most sites your balance sits with the casino between deposit and withdrawal, as at any crypto casino. Licence and terms decide your recourse.
Can I play anonymously at a blockchain casino?
Blockchain transfers are public and linked to your address. Whether you need ID depends on the casino; see no-KYC casinos.
Do I need technical knowledge?
No for deposits and provably fair checks. Smart contract casinos ask more of you: wallets, gas and approvals. See dApp casinos.
Are there fees at blockchain casinos?
You pay the network fee on deposits and withdrawals, and on every bet at smart contract casinos.
